In the geometric progression \(1024,512,256,128,\ldots\), which term is (2)?
Explanation opens after your attempt
Correct Answer
C. दसवाँ पद(10)th term
Concept
From (1024\left\(\frac{1}{2}\right\)^{n-1}=2), \(2^{10-(n-1)}=2^1\), so (n=10). In exams, count decreasing powers carefully.
Why this answer is correct
The correct answer is C. दसवाँ पद / (10)th term. From (1024\left\(\frac{1}{2}\right\)^{n-1}=2), \(2^{10-(n-1)}=2^1\), so (n=10). In exams, count decreasing powers carefully.
Exam Tip
(1024\left\(\frac{1}{2}\right\)^{n-1}=2) से \(2^{10-(n-1)}=2^1\), इसलिए (n=10) है। परीक्षा में घटती घातों को सावधानी से गिनें।
